DISPLAY-FORM.

Specification of Letters Patent.

Patented N (W. 4, 1913.

Application filed June 30, 1913. Serial No. 776,480.

To all whom it may concern:

Be it known that I, EDWARD J. RYAN, a:

citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Display-Forms, of which "the following'is a specification. v This invention relates to a detachable frictionjoint which, is more particularly designed for use in connecting the articulated display forms or figures used in display ng garments in the show windows or rooms of stores.

The arms and hands of such figures which are usually made partly of wax have to beremoved and replaced in'the act of robing or disrobing the forms in order to prevent injuring or niarring the same. The joints of this character as heretofore constructed were {such that they would soon become loose and not stay in the adjusted position thereby not only causing the figures to assume awkward positions but also rendering the form liable to be injured.

Itis the object of this invention to provide a joint for the form sections which will permit the same to .be readil disneinbered or assembled and also ;holc these sections reliablyin any positionto which the same may be adjusted or posed.

In the accompanying drawings: Figure 1 is a verticallongitudinal section of a detachable friction'joinft for display for ns embodying my invention. Fig. 2 a horizontal section thereof. Fig. 3 is a. vertical transverse section taken in line 3-43, Fig. 1. Figs. 4, Sand 6 are perspective viewsof different members ofthe frictional joint between the display form sections.

Similar characters of reference indicate ;0rresponding parts throughout theseveral views.

Although this detachable frictional joint may be employed in various parts .of the display form where it is desired to produce an articulate connection the same is here shown as applied to the upper and lower form sections 1 2 of an arm which are adapted to be detachably connected and also held frictionally in ,any position to which the same may be adjusted.

At the upper'end of .tlie .lOWGr arm section the same is provided with a pivothead 3 .which is preferably of spherical form vand secured to the upper .end of the lower arm section by means of a screw threaded shank d engaging with a correspondingly threaded opening in the lower form section. G11 its upper side the lower pivot head is provided with a radial diainetrical slot 5 which receives an upper pivot head 6 preferably constructed in the form of a flat disk. This pivot disk and pivot head are connected by a transverse pivot bolt, screw or pintle 7 extending diametrically through the lower and upper pivot heads so that these two pivot heads may be turned one relatively to the other about the pivot pin 7 At its outer edge the upper pivot head is provided with a' coupling shank 8 which terminates at itsrear end in a cone-shaped head '9 which tapers rearwardly and has a forwardly facing shoulder 10.

Within a recess 11 formed in the upper arm or form section 1 at a distance from its front end is arranged the catch which is adapted to engage with the coupling shank and operates as" part of the means for detachably connecting the two form sections. This catch preferably comprises two levers 12, 12 which are arranged lengthwise in said recess adjacent to oppositesides thereofand flush with theouter side of the upper form section twojaws 13 projecting inwardly toward each other from the front ends [of the levers and having their opposing faces beveled so that they taper inwardly, and two pairs OfIJlVOlI lugs 15L formed on, the

central parts of these, catch levers and projecting inwardly therefrom so that "they overlap one another. These overlapping lugs of the catch levers are connected by'a transverse bolt, screw or pintle 15 passing through these lugs and the adjacent parts of the upper form section, as shown in Figs.

1 and 2. The catch levers are yieldingly turned in a direction which will cause their jaws to approach each other this beingpref- 'erably effected by means of a single spring 16interposed between thearms of the catch levers and confined against displacementon these levers by means of lugs 17 formed on the inner sides of the rear armsand entering the 'endcoilsofthe spring.

By pushing.thetapering head of the coupling'shank'inwardly between thetwo aws 'of the catch leversthese jaws are illfit separated by the wedging action of the tapering rear face of the conical head on the'fshank and after the shoulder 'of this headpasses inwardly 'beyond the jaws the latter again move toward each ther under the faction of the spring 16 and engage with the'shoulder 10, thereby connecting the upper and lower arm or form sections, When it is desired to detach these form sections it is only necessary to press the inner or rear arms of the catch levers together, thereby separating the jaws on the front arms of the same and permitting the coupling head 9 to be withdra n from between vthe same and the two form sections to be wholly disconnected. lVhile the form sections are thus connected the same can be turned relatively to each other about the transverse axis furnished by the transversepin and bolt 7 and the same can .also be turned about the longitudinal axis tionally the bolt 7 passing transversely through the, same may be tightened as much as desired for presslng the two aws formed (by the bifurcated lower pivothead against opposite sides of the disk shaped upper pivot head.

7 In order to hold the longitudinal coupling shank 8 frictionally in the various positions to which the same may be posed or adjusted when turned about its axis a friction device isfprovided which permits of readily connecting or disconnecting the upper and lower form sections without interfering with this friction device. In its preferred form this last mentioned friction device is constructed as follows 18 represents a sleeve provided with a fiat sided opening 19 in the center or interior thereof which receives a correspondingly flat sided enlargement or hub 20 formed on the central part of the coupling shank between the upper pivot head and the tapering coupling head. In the preferred form of this sleeve its opening is square and the coupling hub is of corresponding form in cross section, as shown in Fig. 3. On its jouterside the friction sleeve 18 is provided with a circumferential intermediate friction disk 21.

22, 23 represent inner and outer friction disks which are arranged on opposite sides of the intermediate friction disk and providedrespectively with circular openings 24,

25 in which the inner and outer ends of the i of fiber or similar friction material are preferably interposed between opposite sides of outer disks,

friction sleeve turn. Washers or disks26 theinterrnediate disk and the inner and The inner friction disk may be secured to the upper form section by any suitable means but preferably by means of two retaining arms 27 which project rearwardly from the inner friction disk on diametrically opposite, sides thereof and along the walls from the recess 11. and provided at the r rear ends with openings 28 which receive the pivot bolt 15 which connects the catch levers. The

outer friction disk isadjustably connected with the inner friction disk by means of a plurality of adjustingscrews 29 extending past the peripheral edge of the intermediate 1 c isk, as shown in Figs. 1, 2 and 3. "Upon tightening the screws 29 the intermediate," disk 1s gripped between the inner andouter:

disk, thereby frictionally resisting the turning movement of the intermediate disk, and

also resisting the turning movement of the j; coupling shank and the parts connected therei with inasmuch as this coupling shankby reason of its square hub engaging with the,

corres ondin l sha 38C]. 0 Jenin in the sleeve a y l a is interlocked with the intermediate disk. 1,

The two form sections, however, are capable without interfering with the upperfrictlon 1 of being freely connected or disconnected mechanisminasmuch as the square hub of the coupling shank is free to slide in and;

out of the friction sleeve in the act of insertmg the coupling shank between the catch levers or detaching the same therefrom.

These means of detachably connecting the two form sections and holding the same. I frictionally in their adjusted position are.

exceedingly simple and inexpensive, they are not liable to get out of order, and they permit of quickly connecting and disconnecting the form sections as well as reliably adjusting them to any desired position or pose.

I claim as my invention: 1. A display form comprising two form sections, a coupling shank arranged on one of said sections, a catch arranged on the other section and engaging with said coupling shank, and means for frictionally retarding the rotation of'said shank relatively to said catch comprising an intermediate friction member detachably connected with said shank, and two friction members engaging with opposite sides of said intermediate member and connected w th said form section on which said catch is mounted.
